1 Claim.

This invention relates to a drinking glass having illuminated bottoni attachment.

it is an object oi the present invention to pro viole an illuniinated` bottom attachment for a drinking glass that is operable upon the drinking glass being tilted to empty the contente thereof as when the child. is 'lrinking from the glass to be lighted and to convey to the child a picture.

it is another object of the invention to proviele a drinking for a child -which will stimulate complete consumption ci the contents of the glass.

It is another object of the invention to prcviale a laminated indicating device in a glass so as to have tv/'o iight indications of diiierent color to he operated. sequence to indicate rst that he glass is one-haii empty and thereafter to n...icate that the glass is completely empty.

@ther objects of the invention are to provide an illuminated attachment for drinking glasses operable as the s is tilted to e ty contents, which oi s e construction, inexpensive to sanitary, easy to attach and fietaoh from glass, compact, durable, oi pleasing appearance and ericient in operation.

For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accor panying ela-wing, in which:

l is a vertical sectional view of the drinking with the light attachment therefor secured in plac on the bottoni end of the glass.

a top planeo view oi the glass. a fragmentary, perspective and collective viev-.f ci the parte which make up the attf'chinent, and adapted to retain the batlamp bulb.

a elevational view of the drinking the thereon and raised i n to empty the saine and with the bottom portion of tac attachment broken away to show the ball elevated. for contact with the lamp bulb in orde to cause the bottom of the glass to ated.

Fig. 5 ie a elevational view oi a modiiied form oi with o. `portion broken away and shown in e ction, this forni of the invention being adapteel to give two different light indications, one when the glass half elnpti;7 and. the other when the glass is fully empty.

Referring new particularly to the Figures 1 to t inclusive, represente a tumbler having a bottom it a depeneing inverted portion l2. This tumbler is oi glass or plastic and is transparent or iro-steel bottom, On the :i 1nating :levi .w which has UVAlient with the threads o the ortion L is cup-shaped member has iaialiy inv/aro'iv extenl'ng shoulder l o which a supporting plate or p socket is Secured by rivets il. This socket it will contain a lamp it. This plate has holes for securing the rivets and diagonally which receive projections ext nung flange iii of the ie socket i6 has a opposite slots :'i f. on the in'vvartlly niemeer i3.

-ange through which the rivets i? '"ihe iiange has depending clip portions 2e and for holding a battery 23 against the socket it when the battery is stripped of paper insulation, the casing will engage with the socket it to establi'li a circuit from one terminal of the battery ivi the socket. The positive terminal of the battery 's indicated at 2 and will be engaged by a clip portieri 23 on an arni 29 that is supported iron i a sleeve Iormation il wl ch can be itted into tle upper enr]` of a sleeve formation rising from the bottom of the cup-shaped member 'The body of the cup-shaped member and the sleeve forniation S2 is preferably iorined of' other insulating material. lo the sl eve ferr-nation a' ol the positive Contact esta?. tween the positive contact or termi bottom of the lamp that the iight will be turned on the picture indicated at be clear to the user of the glass the bottoni of the glass has be attachment will have a tight conteo-tion with the bottom of the cup so that it will be prevented from .being .harmed by moisture or lieuid that might in anv Way short circuit the electrical connections or cause theni to deteriorate. At times when the glasu is to be cleaned, the attachment be separated fr the enel thereof, and. the glass can be cleaned in the usual manner and allowed to dry before the attachment is iixeel again thereto.

In Fig. 5, there is shown an arrangement Whereby an indication Will be made when the contents have been half-emptied from the tumbler and also later another indication Will be made when the tumbler has been fully emptied. According to this form of the invention, 35 represents a tumbler of glass or plastic which has a top enlarged rim S and a bottom 3l. Fitted Within the glass 35 is -a Sylphon device .3-'1 which is adjustable to be extended or to be lifted. 'Thisdevice 3l has a partition 38 near the bottom or the bellows which is supported by a spring 39 extending between a depending pin il! on this partition 38 and a pin 'i2 on a bottom cover 43ftvherebyto-lit the partition as the contents are-removed. When the partition 3S is lifted the contact terminal "iid on a depending bracket t5 mllengageconsecutively contacts it and el. Contact d8 is connected with a lamp i8 so that upon the contact-,"ll'i'en'g'aging with the contact t the light circuit will be vestablished through a batter-y de carriedbythe depending bracket d5 by means of vclips 5I and '52 and'tvhich has the wire E3 leading from one of vthe contacts, v52, to the'lampt and also to a second lamp-5d. The lamp 5d is connectedto the terminal il so vthat upon the contents being completely removed from the collapsible container 3l, the

'springs Will eleva-te the contact @e so that it engages the Contact il and thereby will tur-n on the 'lightkt The spring 3% is of suicient strength to lift the part 33 With the contents partly filling the vsame for the firstcontact @E andithereafter lifting the vpartition 38 after the 'contents have been removed, and so that the lcontact le will engage contact lill. It VWill thus 'be seen lthat one indication can be given when thecontents have been half taken from the drinking tumblenlthat is ablue light d8 can be used, and thereafter a Ared light 5ft will be vturned on when the contents .have been finally removed from the cup.

vThe top part of the collapsible inner container 31 is turned over and-secured to the enlarged top rim 36, in a manner asrindicated at `55.

lIt -should now be apparentthat there has `been Vprovided an attachment for a `drinking glass which Will-illuminate the bottom of vthe tumbler E automatically as the tumbler is turned up to remove the contents therefrom. It Will be seen that this will encourage the drinking of the contents of the tumbler. It Will have particular use With children to encourage their drinking of their liquid food and also to encourage too the drinking of other fluids.

While various changes may be made in the detailed construction, it-shall be understood that such changes shall befvvlithin 'the spirit and scope of the appended claim.

I claim:

An illuminating attachment for tumblers, providing abody member having means for the at -tachn'ient of the same to the bottom of a tumbler, said body member being of cup shape and having upstanding Vbottom sleeve projection, said body member having an inwardly extending Bange, a plate adapted to be supported by the frange, a lamp bulb socket connected to the plate, said plate having a central opening to provide access to the socket, a lampbulb 'fitted into the socket, a contact member having-a sleeve prcection adapted to enter the top end of the bottom sleeve portion, said sleeveportion of the Contact member being ver-ti- 'cally alignedvvith the socket and with the lamp bulb, said lanngz bulb having a bottoni contact, a ball operable in the bottom sleeve 'projection and adapted to extend through the sleeve portion of the contact member to Vengage with 4the bottom contact of thela'rnp'bulb--as the tumbler with `the attachment is inverted, said contact member hay ing a horizontal arm and upstanding clip portion thereon, said socket having a ange with depending clip portions for retaining the battery against 'the socket, said upstanding-clip portion 'of the contact member being engageable with an end terminal of the battery.
